1  Install the remote controller lower case to the wall with the two accessory screws  . 
2  Fasten the screws properly until screw head is lower than the rib and reach the base of remote controller 

lower case to ensure they do not damage the PCB inside the remote controller  . 

 

 

 

3  The feeding-out direction for the remote controller cable can be either via top, left or right side. 
4  Use nipper to cut a notch at the upper case. (Select the intended feeding-out position) 
5  Route the remote controller cable   inside the lower case in accordance with the intended feeding-out 

direction. (Refer to the illustration at below). 

6  Insert firmly the connector of remote controller cable   to connector (CON1) in the upper case circuit board. 

(Refer to the illustration at below) 

7  Secure the remote controller upper case to the lower case with the tabs provided. 

 

 

 

  Lay the drain piping so as to ensure drainage. 

  Use a locally purchased VP20 general rigid PVC pipe (outer diameter ø26) for the drain piping and firmly 

connect the indoor unit and the drain piping using PVC adhesive to ensure that no leakage occurs. 

  Drain piping located indoor should always be insulated by wrapping with locally purchased insulation (foamed 

polyethylene with a thickness of 10 mm or more). 

  The drain piping should have a downward gradient (1/50 or more) and should be secured by using pipe hanging 

equipment to avoid creating hills or traps partway. 

  Should there be any obstacle preventing the drain piping from being extended smoothly, the drain piping can be 

raised outside of the main unit as shown in the illustration below. 

 

 

Strictly do not install and extend the drain piping from the main unit drain water outlet horizontally or upward or raised it 20 cm or more.
Doing so may result in poor drainage or drain motor failure.

  Pour approximately 600 cc of water into the drain pan of the main unit using a squeeze bottle, etc. 

  Press the drain test run switch on the control board in the control box to start the drain motor and check whether 

the water drains normally. (The drain motor operates for approximately 5 minutes and then stops automatically.) 
(See the diagram for “Connecting the Indoor/Outdoor Connection Cable”.) 

 

 

 

  After the piping is connected, insulate as shown in the illustration. 

 

 

 

  Remove the control box cover and lead the 

connection cable into the control box. 

  Check the color of the wires on the terminal board 

and secure them with screws. 

  Secure the outer sheath of the connection cable 

with the cord clamp. 

  Reattach the control box cover to its original 

position. 

 

 

When the wall is hollow, please be sure to use the sleeve 
for tube ass’y to prevent dangers caused by mice biting the 
connection cable. 

 

  Connection cable between indoor unit and 

outdoor unit should be approved polychloroprene 
sheathed 4 x 1.5 mm

2

 flexible cord, designation 

type 60245 IEC 57 (H05RN-F) or heavier cord. 
Allowable connection cable length of each indoor 
unit shall be 30 m or less. 
o

  Ensure that the terminal numbers on the 

indoor unit are connected to the same 
terminal numbers on the outdoor unit by the 
right coloured wires as shown in the diagram. 

o

  Earth lead wire should be longer than the 

other lead wires as shown in the diagram for 
electrical safety purpose in case the cord slips 
out from the anchorage. 

  Secure the cable onto the control board with the 

holder (clamper). 
 

 

  Ensure the colour of wires of outdoor unit and the 

terminal Nos. are the same to the indoor’s 
respectively. 

  Earth wire shall be Yellow/Green (Y/G) in colour 

and longer than other AC wires for safety reason.

  If an awning is built over the unit to prevent direct sunlight or rain, be careful that heat radiation from the 

condenser is not obstructed. 

  There should not be any animal or plant which could be affected by hot air discharged. 

  Keep the spaces indicated by arrows from wall, ceiling, fence or other obstacles. 

  Do not place any obstacles which may cause a short circuit of the discharged air. 

  If piping length is over the [piping length for additional gas], additional refrigerant should be added as shown in 

the table.

Example: For E9***** 
If the unit is installed at 10 m distance, the quantity of additional refrigerant should be 50 g .... (10-7.5) m x 20 g/m = 
50 g. 
 

At the best location, start installation according to 
Indoor-Outdoor Unit Installation Diagram. 
1  Fix the unit on concrete or rigid frame firmly 

and horizontally by bolt nut. (ø10 mm). 

2  When installing at roof, please consider strong 

wind. 
Please fasten the installation stand firmly with 
bolt or nails.

Please make flare after inserting flare nut (locate at 
joint portion of tube assembly) onto the copper pipe. 
(In case of using long piping) 
Connect the piping 

  Align the center of piping and sufficiently tighten 

the flare nut with fingers. 

  Further tighten the flare nut with torque wrench in 

specified torque as stated in the table. 

 

 
Decide piping length and then cut by using pipe cutter. 
Remove burrs from cut edge. Make flare after 
inserting the flare nut (locate at valve) onto the copper 
pipe. Align center of piping to valve and then tighten 
with torque wrench to the specified torque as stated in 
the table. 

Do not overtighten, overtightening may cause gas leakage.
